IPSec tunnel problem work without configuration on asa

Hello world

I have a problem with one asa version 8.4.3.

I have a tunnel if I do not set up the tunnel and if I configure it does not mount to mount with a remote site

someone that you already see that? With version 8.2, we had no worries, but since he problem of migration.

Tunnel configuration we get this error:

IKEv1]: Group = x.x.x.x IP x.x.x.x, QM WSF error = (P2 struct & 0x49ba5a0, mess id 0xcd600011).

[IKEv1]: Group = x.x.x.x, IP = x.x.x.x, removing counterpart of correlator table failed, no match!

Thanks for your response

I have never seen as the result of an ASA simple upgrade, but in general there are a number of things that could cause this problem. Generally, this is one unidentified peer or peer without valid card crypto trying to establish VPN site site that generates the message above.

Please take a look at this troubleshooting guide.

If it does not help. Thanks for posting your script

How to set up adoption to work without configuring patch FS - 12.2.4

Hello Experts,
I need your suggestion in 12.2.4 ebs cloning processes,
Database - 11.2.0.3
Application - 12.2.4
Delta 6
We have a daily process of clone in environment and it is completely automated through scripting shell, it takes 2 hours to clone us pre-production of Prod.
Steps for cloning-
1 clone of database via a level VM snap technologies
2. clean the fnd nodes and run autoconfig on database layer
3 - rsync happens parallel for the application tier
4 - once rsync ends, run us autoconfig on the applications node and run the steps to clean some clone of post production of information and to define options profile
5 - communicate to users
We cannot apply patches on this forum that we have adopted set up right now (as the fs patch is not configured), in order to install the patch fs, it will take another 4 to 6 hours. According to the company, the clone that happens daily requirement, then this environment comes down to 20 hours to next clone. So 4-6 hours work time to configure patch fs for adoption will not help
Requirement is - we want to adopt to work on this 12.2.4 environment without patch fs. We apply all the patches in /hotpatch mode, I guess Run fs is necessary for the patches to be applied in /hotpatch.
Can someone please advice/suggest if we can achieve this without configuring Patch fs. Since the data are very recent on this pre-production, it'll be great we can activate the ability to patch on that to test the company's problems
Thank you

Hello

According to the link below, you can use a single filesystem for development or test systems.

https://blogs.Oracle.com/stevenChan/entry/12_2_ad_txk_delta

However, it is preferable to full adoption patch cycle allows to apply patches on test systems.

Prepare the patch on the cloned environment file system requires no downtime. You can do this even if the application is running.

From my experience when a tunnel is launched on one side, but it is not on the other hand, that the problem is with an inconsistency of the isakmp and ipsec policies, mainly as ipsec policies change sets and corresponding address with ASA platform when a tunnel is not a statically defined encryption card he sometimes use the dynamic tag to allocate this vpn connection. To check if this is the case go ahead and make a "crypto ipsec to show his" when the tunnel is active on both sides, see on the SAA if the corresponding tunnel is the static encryption card set or if it presents the dynamic encryption card.

I advise you to go to the settings on both sides and ensure that they are both in the opposite direction.

Site to Site VPN working without Crypto Card (ASA 8.2 (1))

Hi all

Find a strange situation on our firewall to ASA5540:

We have a few Site to Site VPN and also activate on the ASA VPN cleint, all are working properly. But finding that a VPN from Site to Site is running without crypto map configuration. Is this possible?

I tried to erase isa his and claire ipsec his then VPN came once again. Tested too, it's the ping requests to a remote site through the VPN.

I saw there are config tunnel-group for VPN but saw no card crypto and ACL.

How is the firewall knows what traffic should be encrypted for this VPN tunnel without crypto card?

This is the bug?

Thanks in advance,

It can be an easy vpn configuration.

Could you post output config operation remove any sensitive information. This could help us answer your question more specifically.

IPSec tunnel do not come between two ASA - 5540 s.

I've included the appropriate configuration of the two ASA lines - 5540 s that I'm trying to set up a tunnel of 2 lan lan between. The first few lines show the messages that are generated when I try to ping another host on each side.

Did I miss something that will prevent the tunnel to come?

Strange problem in IPSec Tunnel - 8.4 NAT (2)

Helloo all,.

This must be the strangest question I've seen since the year last on my ASA.

I have an ASA 5540, who runs the code of 8.4 (2) without any problem until I ran into this problem last week and I spent sleepless nights with no resolution! Then, take a deep breath and here is a brief description of my setup and the problem:

A Simple IPSEC tunnel between my 8.4 (2) ASA 5540 and a Juniper SSG 140 6.3.0r9.0 (road OS based VPN) screen

The tunnel rises without any problem but the ASA refused to encrypt the traffic but it decrypts with GLORY!

Here are a few outputs debug, see the output and a package tracer output that also has an explanation of my problem of NAT WEIRD:

As you can see, there is no echo response packet at all because the package may not be wrapped while he was sent to.

I'm Karen with it. In addition, he is a firewall multi-tenant live production with no problems at all outside this for a Juniper ipsec tunnel!

Also, the 192.168.10.0/24 is another remote network of IPSec tunnel to this network of 10.2.4.0/28 and this IPSEC tunnel has a similar Juniper SSG 140 screen os 6.3.0r9.0 at the remote end and this woks like a charm with no problems, but the 171 is not be encrypted by the ASA at all.

If someone could help me, that would be greatt and greatly appreciated!

Thanks heaps. !

Perfect! Now you must find something else inside for tomorrow--> forecast rain again

NAT in the IPSec tunnel between 2 routers x IOS (877)

Hi all

We have a customer with 2 x 877 routers connected to the internet. These routers are configured with an IPSec tunnel (which works fine). The question is the inbound static NAT translation problems with the tunnel - port 25 is mapped to the address inside the mail server. The existing configuration works very well for incoming mail, but prevents users from access to the direct mail server (using the private IP address) on port 25.

Here is the Config NAT:

nat INET_POOL netmask 255.255.255.252 IP pool

IP nat inside source map route INET_NAT pool INET_POOL overload

IP nat inside source static tcp 10.10.0.8 25 25 expandable

IP nat inside source static tcp 10.10.0.8 80 80 extensible

IP nat inside source static tcp 10.10.0.8 443 443 extensible

IP nat inside source static tcp 10.10.0.7 1433 1433 extensible

IP nat inside source static tcp 10.10.0.7 extensible 3389 3389

allowed INET_NAT 1 route map

corresponds to the IP 101

access-list 101 deny ip 10.10.0.0 0.0.0.255 192.168.1.0 0.0.0.255

access-list 101 permit ip 10.10.0.0 0.0.0.255 any

On the SAA, I would setup a NAT exemption, but how do I get the same thing in the IOS?

See you soon,.

ASA ASA from Site to Site VPN IPSec Tunnel

Any help would be greatly appreciated...

I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.

Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24

Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24

Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.

Internet access works very well in all workstations of this site. A static route is configured to redirect all traffic to a public router upstream.

Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address. A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA. A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253. This device then performs its own private Public NAT. Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)

The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24). The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254). The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem. However, all traffic passing on networks ICMP does not end and the Syslog reports the following-

Site #1-

6 January 19, 2011 15:27:21 302020 ZEFF-SB-01_LAN 1 10.1.1.51 0 Built of outbound ICMP connection for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1

6 January 19, 2011 15:27:23 302021 10.1.1.51 0 ZEFF-SB-01_LAN 1 Connection of ICMP disassembly for faddr 10.1.1.51/0 gaddr ZEFF-SB-01_LAN/1 laddr ZEFF-SB-01_LAN/1

Site #2-

6 January 19, 2011 15:24:47 302020 10.1.1.51 0 10.0.0.30 1 Built of outbound ICMP connection for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1

6 January 19, 2011 15:24:49 302021 10.0.0.30 1 10.1.1.51 0 Connection of disassembly for faddr gaddr laddr 10.1.1.51/0 10.1.1.51/0 10.0.0.30/1 ICMP

It's the same for any form of traffic passing over the tunnel. The ACL is configured to allow segments of LAN out to any destination. At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).

Anyone can shed light on a possible cause of this problem?

Thank you

Nick

did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?

Please provide the following information

-set up the tunnel

-show the isa cry his

-show the ipsec cry his

-ping of the site 1 site 2 via tunnel

-capture "crypto ipsec to show his" once again

-ping from site 2 to 1 by the tunnel of the site

Well, I think it is a NAT ordering the issue.

Basically as static and this NAT rule-

NAT interface dynamic obj - 0.0.0.0 source (indoor, outdoor)

are both in article 1 and in this article, it is done on the order of the rules so it does match the dynamic NAT rule rather than static because that seems to be higher in the order.

To check just run a 'sh nat"and this will show you what order everthing is in.

The ASA is working its way through the sections.

You also have this-

NAT source auto after (indoor, outdoor) dynamic one interface

which does the same thing as first statement but is in section 3, it is never used.

If you do one of two things-

(1) configure the static NAT statement is above the dynamic NAT in section 1 that is to say. You can specify the command line

or

(2) remove the dynamic NAT of section 1 and then your ASA will use the entry in section 3.

There is a very good document on this site for NAT and it is recommended to use section 3 for your general purpose NAT dynamic due precisely these questions.

It is interesting on your ASA 5505 you duplicated your instructions of dynamic NAT again but this time with article 2 and the instructions in section 3 that is why your static NAT works because he's put in correspondence before all your dynamic rules.

The only thing I'm not sure of is you remove the dynamic NAT statement in article 1 and rely on the statement in section 3, if she tears the current connections (sorry can't remember).

Then you can simply try to rearrange so your static NAT is above it just to see if it works.

Just in case you want to see the document here is the link-

ASA 8.6 - l2l IPsec tunnel established - not possible to ping

Hello world

I have a problem of configuration of the CISCO ASA 5512-x (IOS 8.6).

The IPsec tunnel is created between ASA and an another non-CISCO router (hereinafter "router"). I can send packets ping from router to ASA, but ASA is NOT able to meet these demands. Sending requests of ASA is also NOT possible.

I'm trying to interconnect with the network 192.168.2.0/24 (CISCO, interface DMZ) premises and 192.168.3.0/24 (router).

The CISCO ASA has a static public IP address. The router has a dynamic IP address, so I use the dynamic-map option...

Here is the output of "show run":

Do you have an idea that I am wrong? Probably some bad NAT/ACL I suppose, but I could always find something only for 8.4 iOS and not 8.6... Perhaps and no doubt I already missed the configuration with the unwanted controls, but I've tried various things...

Please, if you have an idea, let me know! Thank you very much!

Hello

I've never used "global" option in ACL, but it looks to be the origin of the problem. Cisco doc.

"The global access rules are defined as a special ACL that is processed for each interface on the device for incoming traffic in the interface. Thus, although the ACL is configured once on the device, it acts as an ACL defined for Management In secondary interface-specific. (Global rules are always in the direction of In, never Out Management). "

You ACL: access-list extended dmz_acl to any any icmp echo

For example, when you launch the ASA, there is an echo response from the router on the external interface--> global can block.

Then to initiate router, the ASA Launches echo-reply being blocked again.

Try to add permit-response to echo as well.

In addition, you can use both "inspect icmp" in world politics than the ACL.

If none does not work, you can run another t-shoot with control packet - trace on SAA.

Cisco's ASA IPsec tunnel disconnects after a while

Hi all

I've set up an IPsec tunnel between sonicwall pro road and cisco ASA 5510. The well established tunnel and two subnets can access each other.

I then added a static route to a public ip address on the sonicwall ipsec policy, so that all traffic to this ip address will go through the IPsec tunnel. It also works very well.

But the problem is aftre tunnel Ipsec sometimes breaks down, and then I need to renegotiate the ipsec on sonicwall to restore the tunnel.

This happens twice a day. I'm whther fear that this behavior is because of problems with config. I'm pasting my ASA running Setup here. Plese give some advice.

I guess you have typo in the configuration of the ASA?

L2L 192.168.5.0 ip extended access-list allow 255.255.255.0 192.168.10.0 255.255.255.0
list access extended extended permitted host ip voip pubic ip 192.168.10.0 255.255.255.0

Can you confirm that you have configured instead the following:

access-list l2l extended permitted host ip voip pubic ip 192.168.10.0 255.255.255.0

Moreover, even if the crypto map tag says easyvpn; peer address is correct to point 1.1.1.2

In addition, don't know why you have the following configuration (but if it is not necessary I suggest to be removed and 'clear xlate' after the withdrawal):

NAT (outside) 1 192.168.10.0 255.255.255.0

Finally, pls turn off keepalive to SonicWall.

If the foregoing still don't resolve the issue, can you try to remove the card dynamic encryption of the ASA (no map mymap 30000-isakmp ipsec crypto dynamic easyvpn), release the tunnel and try to open the tunnel between the ASA and SonicWall and take the exit of "show the isa cry his ' and ' show cry ipsec his» I'm curious to see why he is always referred to the easyvpn crypto map. When you remove the dynamic encryption card, dynamic vpn lan-to-lan of remote access client does not work.

IPsec Tunnel is in place and I can access the server on the other side via the beach of NATTED, for example a server behind the checkpoint with the IP 10.90.55.11 is accessible behind the ASA as 4.4.4.11, the problem is that I have never worked on a Checkpoint Firewall and servers/Server 4.4.4.11 that I can't connect to my environment to that checkpoint is configured with a Tunnel interface that is also supposed to to make NAT because of the superimposition of networks, at one point, I added an access to an entire list and bidirectional routing has been reached, but I encountered a new problem, I could not overlook from my servers public became unaccessecable, since all traffic was encrypted and get dropped to VPN: ipsec-tunnel-flow... for now the Tunnel is up and I can access the server via NAT 4.4.4.11, but can't access my internal servers. What did I DO WRONG (also, I don't have access to the Checkpoint Firewall (PE)) how their installation would be or how it should be to allow bidirectional routing?

unless I include any any on my access-list and the problem with that is  that my Public servers then get encrypted from the OUTSIDE interface  unless you know of a way to bypass the VPN

No, u certainly shouldn't allow 0.0.0.0 for proxy ACL. Again, your config is very good. In addition, package account, this show that traffic is going throug the tunnel in two ways:

#pkts program: 3207

#pkts decaps: 3417

Also, looking at the meter, I can guess that some of the traffic comes from the other site, but does not return back (maybe that's where you can not connect from behing Checkpoint). If you say that 0.0.0.0 solved the problem, are there no other NAT rules for subnet behind ASA, so the server IP, for which you are trying to connect behind the checkpoint, translates into something else (not the beach, included in proxy ACL), when to come back?

Cisco ASA - l2l IPSEC tunnel two dynamic hosts

Hello

I have two firewall Cisco ASA an i want to made a l2l between two ipsec tunnel, the problem is that both parties have a dynamic IP, on both sides I have configured dyndns, can I did an ipsec tunnel using dyndns name such as address peer?

Hello

ASA supports only the RFC compliant method for updates used with dynamic DNS, not updates HTTP, such as dyndns.org and others use.
i.e. https://tools.cisco.com/bugsearch/bug/CSCsk25102/?reffering_site=dumpcr

On ASA, it is not possible to configure the tunnel between two dynamic peers.
You will need to have a static end to configure static to dynamic IP.

For routers, you can follow this link.
I hope this helps.

Kind regards

IPSec Tunnel permanent between two ASA

Hello

I configured a VPN IPSec tunnel between two ASA 5505 firewall. I want to assure you as the IPSec tunnel (this is why the security association) is permanent and do not drop due to the idle state.

What should I do?

Thanks for any help

Yves

Disables keepalive IKE processing, which is enabled by default.

(config) #tunnel - 10.165.205.222 group ipsec-attributes

KeepAlive (ipsec-tunnel-config) #isakmp disable

Set a maximum time for VPN connections with the command of vpn-session-timeout in group policy configuration mode or username configuration mode:

attributes of hostname (config) #-Group Policy DfltGrpPolicy
hostname (Group Policy-config) #vpn - idle - timeout no

attributes of hostname (config) #-Group Policy DfltGrpPolicy
hostname (Group Policy-config) #vpn - session - timeout no

Thank you

Ajay
